Title: Improvements in or relating to the extinction and/or prevention of fires on aircraft
IPC: A62C35/60
Filed: 1931-01-22
Abstract: 366,704. Fire-extinguishing apparatus. BLAKEBOROUGH, R. A. and DENNE, R. A., Woodhouse Works, Brighouse, Yorkshire. Jan. 22, 1931, Nos. 2225 and 13457. [Class 47 (ii).] A fire-extinguisher comprises a collapsable container which, in use, is ruptured or pierced and is then collapsed by applied pressure to eject its contents. As shown, a casing a is subdivided by a perforated partition a<3>. A container e, of thin lead, for example, is placed in one end of the casing, and that end is closed by a cap a<2> provided with a sealing capsule f. The mouth of the container is reinforced by a ring e<1> and is soldered to the casing. The chamber b at the other end of the casing is charged with a fluid pressure medium through a valve c. The cap a<2> carries a tubular member g in which a spring-pressed hollow pierced h is restrained by a latch lever j. The latter is held in restraining position by a cartridge k adapted to be fired electrically. The piercer is connected to a pipe line by means, such as a coiled tube m, allowing movement of the piercer. In use, firing of the cartridge allows the piercer to rupture the capsule f. The pressure in chamber b then acts to collapse the container e. The cartridge may consist of a glass vessel or a two-part telescopic device housing an explosive charge. In a modification, the piercer is restrained by a catch on a spring adapted to be moved aside by explosion of the cartridge. In another modification, the member g is replaced by a cap provided with a nozzle and a hand-operated piercer. In another modification, the chamber b is connected to a suitable source of compressed fluid. In another modification, Fig. 4, the chamber b houses a combustible cartridge p adapted to be ignited electrically. The collapsable container e is closed at both ends, and the outer end is formed with a skirt and a flange c<3> nipped between the cap a<2> and a packing ring s. The cartridge is arranged first to burn quickly, to force the container e against a fixed piercer h<4>, and then to burn at a slow uniform rate, to generate pressure for collapsing the container. Where an extinguishing medium of a very volatile nature is employed, the container may be provided with a protective casing designed to resist deformation of the container by abnormal internal pressures, but to permit access to the container of the applied collapsing pressure.

Abstract: 705,431. Welding. GENERAL ELECTRIC CO., Ltd., and SOWTER, A. B.. Aug. 11, 1952 [Sept .  28, 1951], No. 22725/51. Class 83 (4)  A method of attaching a stranded, braided or the like electric conductor or cable of pressure weldable material to a lug or connecting device of plate or tag form also of pressure weldable material comprises holding the conductor or cable and applying pressure across the superposed conductor or cable and the lug or connecting device to cause sufficient plastic flow of the materials to weld them together the holding of the connector or cable elements preventing the elements from splaying out during the welding process. In an embodiment an aluminium cable 1 consisting of strands 2 is covered by an insulating covering 3 which is stripped back from the end of the cable where it is to be welded to an aluminium lug 4. The lug has gripping ears 5, a hole 6 for engaging a terminal and a hole 7 through which the end of the cable 1 is passed. Before passing through the hole 7 the strands 2 of the cable are cleaned by mechanical scratch brushing using a rotary scratch brush by first untwisting the strands, brushing and then retwisting the strands. The welding tools comprise an upper tool 8 having a flat end face 10 and an anvil 9. The strands are compacted in the hole 7 during the welding operation and welded to the lug mainly at points X and Y. In another embodiment the top tool 17, Fig. 3, has a welding tip 18 having a flat rectangular welding face 19 and co-operates with the anvil 16 which has a semi-circular groove 15 the cross sectional area of which is substantially equal to the sum of the cross sectional areas of the cable strands 11. During welding the strands are compacted in the groove and the cable 11 and tag 12 welded together the finished weld having the appearance as shown in Fig. 4. The final thickness across the weld is about 0.040 inches. In a modification the hole in the tag may be dispensed with and the welding effected as shown in Fig. 5. In a further embodiment the tool tip 18 has a flat part 20 and a curved part 21, Fig. 7, and this varies the reduction produced over the face of the tool and gives adequate strength at certain points and adequate welding at other points.

Title: Improvements to ball games
IPC: A63B71/04
Filed: 1964-01-21
Abstract: 1, 046, 082. A range for practicing golf and other ball games. PRODUCT INVESTORS CORPORATION, Ltd. Jan. 21, 1964 [Aug. 13, 1963], No. 2592/64. Heading A6D. Apparatus for use in practicing a ball game comprises an enclosure having a position 16 at one end from which a ball is projected towards a target screen 12, a film of a field of play being projected on to the screen under the control of a computer which receives impulses corresponding to the time the ball takes to travel from the playing position to the target screen, and transmits corresponding signals to the projector 22 so that the amount of film moved through the projector after every projection of the ball corresponds to the force with which the ball is projected. In the preferred embodiment the game simulates golf, and the film projected is a golf course comprising a number of holes. The ball's flight time is measured by means of photoelectric or acoustic devices mounted adjacent the tees 20, 21 to detect the delivery of a stroke to the ball, in conjunction with light sources 38-42 and photosensitive devices 33-37 mounted adjacent the screen. In addition, the photo-electric devices 33-37 and 38-42 control spot lights 27-31, so that depending on which of the photo-electric devices senses the arrival of the ball at the screen, a spot of light is projected on to the target to indicate the position of the ball on the fairway projected thereon. Legends on the film indicate the distance of the ball from the hole, and also indicate the eventual arrival of the ball on the putting green. In using the apparatus each player continues to drive successive shots from the teeing position 16 towards the screen, thus causing progressive movement of the film through the projector, until the markings on the film indicate the arrival of the ball on the putting green. Finally, each player putts the ball from a position on the floor 60 of the enclosure towards a target cup 61, the position from which the putt is made being dictated by the nearness of the spottiglit representing the ball to the projected hole, and by the particular hole of the course which is being aimed for. A control panel 48 is provided for controlling the computer to return the film to the particular tee in play after each player has holed the ball, and for advancing the film to the next tee after every player has holed the ball. Provisions are also made for using the apparatus to continuously practice driving the ball away from the tee, in which case the appropriate switch on panel 48 is thrown to automatically return the film to the teeing position after every shot.

An angle-modulated radio link comprises successive repeaters, all of which include a super-regenerative amplifier, all those amplifiers receiving signals constituted by wave trains acting as self-quenching oscillators, and the terminal receiver selects only one of the frequency bands of the spectrum radiated by the last repeater (the centre frequencies of these bands differing by the quench frequency). If the transmitter radiates a continuous, frequency-modulated, wave the amplifier of the first repeater acts as a separately-quenched oscillator, but if the transmitter radiates a chopped frequency-modulated wave then all the amplifiers act as self-quenching oscillators. The terminal receiver may include a super-regenerative high-frequency amplifier operating at the quench frequency, the desired frequency band being filtered from the received spectrum in the intermediate frequency stages of the receiver.
